The Role

Run rapid experiments, build prototypes, conduct lightweight user research, design AI-native experiences that manage model limitations, and collaborate with PMs and engineers to iteratively ship coherent, user-focused MVPs while maintaining long-term product vision.
Summary Generated by Built In

Join the AI revolution. We’re building an all-in-one AI platform to help teams do their best work and automate every routine task you can think of. We’re looking for problem-solvers to turn powerful AI into an easy, no-code tool for teams everywhere.

Main Responsibilities

  • Work closely with Product Managers and Engineering to navigate ambiguity and shape solutions. Take initiative and help define what needs to be done.

  • Lead problem discovery, not just execute solution design.

  • Use continuous, lightweight discoveries, run rapid experiments, build prototypes, and validate design decisions before building.

  • Talk to users regularly through low-effort, AI-assisted research activities. Focus on what can be done with available resources and time.

  • Design AI-native experiences that create trust while accounting for AI hallucinations, latency, and model limitations.

  • Think system-first and ensure the product ecosystem feels coherent and consistent.

  • Balance speed and quality while shipping imperfect MVPs in small increments, continuously improving with user feedback while maintaining the long-term product vision.

  • Balance several tasks at once, prioritize activities effectively, and ensure deadlines and quality standards are met.

  • Share feedback, improve design patterns, and help scale the overall product experience.

Core Requirements

  • Proven startup experience with an ability to adapt and drop rigid processes.

  • Experience designing AI-powered or complex systems, demonstrating a systems-thinking approach over isolated feature design.

  • Show clear communication with a proficiency in explaining trade-offs, constraints, and reasoning behind design decisions.

  • Capability to identify key assumptions in a product idea and validate them quickly through experiments, prototypes, or user insights.

  • Experience defining success metrics and using real product data to guide design iteration.

  • Hands-on experience with user research methods, analytics, usability testing, user interviews, or related UX research techniques.

  • Ability to drive the design process independently while remaining a highly collaborative team player.

  • Focus on both user problems and organizational outcomes, rather than just UI deliverables.

  • Basic technical understanding and familiarity with modern web technologies.

  • Highly curious about AI and how UX can make those systems understandable and trustworthy.

Bonus Points

  • Active utilization of AI tools to accelerate and improve your own design process.

NOTE: We look forward to your portfolio, particularly highlighting projects focused on complex SaaS products, multi-step user workflows and mobile applications. Case studies showcasing end-to-end product design work are highly appreciated.
